Help Please

We have since moving gone from BT/02 to talk-talk..

they came and fitted the adsl box and gave us a new phone number yesterday,, we switched on all the puters, 1 Netbook 2 Laptops and 2 Main computers..

All have latched on to the wire free bit except my laptop, it says connected but local only :Angry:

Does anybody know of a setting on my laptop that I have to do or go into so as mine works?

Just seems strange that all the others did not need tweekering, and worked straight away.

If some one who is switched on and could talk me through would be so kind as to send me their phone number, I would phone them..

Thanks.
